Answer 1

Answer:

y = 2x

Step-by-step explanation:

Take two random points on the line. I'm going to take (1, 2) and (2, 4) for this.

Use y = mx + b. Your goal is to find m and b, since you already have x and y.

Pardon my bad handwriting. And sorry I don't know another faster way

Answer 2

Answer:

m = 2

Step-by-step explanation:

If we take two points from the graph, say (1, 2) and (2, 4)

we can use the formula (y2 - y1) / (x2 - x1).

y2 is the y of the second point, and y1 is the y of the first point, and same goes for x2 and x1.

If we use this formula, we get (4 - 2) / (2 - 1)

2 / 1

= 2

m = 2
